Importing Data from DLI

Data importing from DLI is supported for table datasets.

To import data from DLI, select the DLI queue, database, and table name. The schema (column name and type) of the selected table must be the same as that of the dataset. The schema of the selected table can be automatically obtained.

• Queue Name: All DLI queues of the current account are automatically displayed. Select the required queue from the drop-down list.
• Database Name: All databases are displayed based on the selected queue. Select the required database from the drop-down list.
• Table Name: All tables in the selected database are displayed. Select the required table from the drop-down list.

The default queue of DLI is used only for experience. Different accounts may preempt resources. Therefore, resources need to be queued. You may not be able to obtain required resources each time to perform related operations.

DLI supports schema mapping. That is, the schema field name of the imported table can be different from that of the dataset, but the type must be the same.
